Thanks, I always wanted one, 20 years ago it was a dream, now I have a 1996 4.0 XK8 Coupe, 120,000 miles, good history and all stamps in the book. Transmission fluid changed at 75,000 miles according to receipt in the mountain of paperwork. Its a problem with poor power to pull away, and if I floor it, there is like clutch slip & I hit 7000 RPM.
I took the sump off the gearbox tonight to see if it was full of metal. I found, what I believe is the original 1996 filter & there was a little fine power on the magnets, but no metal bits. Although i spilt a bit, i only recovered about 5l of fluid, so I've ordered new filter & getting new Esso LT71141 oil tomorrow & going to put it back together to see what happens. Yes, I still got a smile.

Appreciated, i know mine is the older ZF 5HP box, with the famous A Drum, but everything can be fixed, may take time & a lot of work, but the smile at the end is always worth it.

I just dropped the pan on my ZF 5HP-24 and it also had the original filter (which I left in there), the fluid looked like yours and there were no shavings. My trans would slip on hard acceleration too. I installed the Aftermarket dip stick while I was there: 5HP24 Dip Stick
The fluid change made a big difference! No slip!
I also did both sets of tensioners and chains, metal water pump and thermostat housing too BTW. Big difference in performance.

OK, it took 4 try's to get the oil level right, mainly due to temperature reaching 50 & them having to wait for over an hour for it to cool down to try again. Finally on the 4th go, just as the temperature hit 40, there it was, a full gearbox, all perfectly level, having previously run through the gears twice, it started to dribble out. Out came the fill pipe, out came the temperature probe and the fill plug was put back in & nipped tight.
Due to time & weather, tomorrow should see the wheels back on the ground & a test run to establish a result.....

I'm leaning towards A drum failure. My 99 xk8 was slipping like yours and would go to limp mode. It showed gearbox failure and a code for 2nd gear improper ratio. I don't recall the code #. I had no metal in the pan either. Removed transmission opened it up and found that the A drum had failed. The top or the drum was separating but hadn't broken of the drum. It separated enough to cause the clutch to slip but since it hadn't broken off yet there wasn't any chunks in the pan. If this is the case you lucky because you can repair before more damage is done. I don't know if this is your case but I feel it is a strong possibility. I would still check your codes first to see what you get. Good luck.

I read that the TQ needs to be unbolted first? Any information?
